Abstract

A structure of preventing door opening in vehicle collision may include a handle housing including a housing stopper, a door handle rotatably mounted around a door handle rotation axis on the handle housing, and of which a rotation contact end portion formed at one end portion thereof, and a blocking lever assembly including a blocking lever rotatably coupled to the handle housing and having an inertia portion formed on a portion of the blocking lever, and an assist lever selectively protruded from the blocking lever, wherein, when the blocking lever assembly is rotated by an external impact applied to the blocking lever assembly, the assist lever protrudes out of the blocking lever to be caught by the housing stopper and positioned in a movement path of the rotation contact end portion.

First claim

What is claimed is:

1. A structure of preventing door opening in vehicle collision, the structure comprising:
a handle housing including a housing stopper;
a door handle rotatably mounted around a door handle rotation axis on the handle housing, wherein a rotation contact end portion is formed at an end portion of the door handle; and
a blocking lever assembly including:
a blocking lever rotatably coupled to the handle housing and having an inertia portion formed on a first end portion of the blocking lever; and
an assist lever slidably mounted in a second end portion of the blocking lever and configured of selectively protruding from the second end portion of the blocking lever;

wherein, when the blocking lever assembly is rotated by an external impact applied to the blocking lever assembly, the assist lever protrudes out of the blocking lever to be caught by the housing stopper and positioned in a movement path of the rotation contact end portion.

2. The structure of claim 1 , wherein the blocking lever assembly further including a lever spring elastically biasing the blocking lever away from the movement path of the rotation contact end portion.

3. The structure of claim 2 , wherein the second end portion of the blocking lever includes a blocking lever protrusion that contacts with the rotation contact end portion when the rotation contact end portion of the door handle presses the assist lever.

4. The structure of claim 2 , wherein the rotation contact end portion of the door handle is formed obliquely.

5. The structure of claim 2 , wherein an end portion of the assist lever which protrudes out of the second end portion of the blocking lever is formed obliquely.

6. The structure of claim 1 , wherein the blocking lever assembly further including a lever spring that rotates the blocking lever assembly when the rotation contact end portion presses the assist lever to move the blocking lever assembly out of the movement path of the rotation contact end portion.

7. The structure of claim 1 , wherein the blocking lever assembly further including an assist lever spring for elastically supporting the assist lever in a predetermined direction.

8. The structure of claim 7 , wherein the assist lever spring is mounted inside the second end portion of the blocking lever.

9. The structure of claim 1 , wherein the second end portion of the blocking lever has a lever insert portion into which the assist lever is slidably mounted to enable the assist lever to move through the lever insert portion.

10. The structure of claim 1 ,
wherein the blocking lever assembly further including an assist lever guide pin, and
wherein the assist lever has a guide slot into which the assist lever guide pin connected to the blocking lever is inserted.

11. The structure of claim 1 , wherein a blocking stopper is formed on a portion of the blocking lever to limit rotation of the blocking lever assembly in contacting with the handle housing.

12. The structure of claim 1 , wherein the blocking lever assembly further including a lever pin rotatably coupling the blocking lever assembly to the handle housing.

13. The structure of claim 1 ,
wherein the blocking lever is in a shape of “L”,
wherein the first end portion of the blocking lever includes the inertia portion, and
wherein the assist lever is slidably mounted in the second end portion of the blocking lever.
